I have three Brooks Emerson mass flow controllers, but I can't control them
using some Excel macros and the SmartDDE because Windows XP doesn't
recognize the controllers by the COM port.
How can I solve this problem?
I also need the help file that comes with SmartDDE (when I installed the
program no help file was created). Where can I find it?
Where can I find the document regarding the HART protocol-based commands,
Brooks part no. 541-C-053-AAA?
Thanks in advance.
